F. D. SPEAR S I GNAL LANTERN Filed April 24,. 1925 2 Sheets-Sheet 2 y flat gasket 22 affords a tight joint and yet it is so arranged that the top can be closed down without tilting the globe as is neces'- sary in many lanterns. lVhen the lantern is 5 swung, in giving varying signal and especially in ufpward movement,it becomes necessary to urnish an additional air supply to the flame from the direction of the topl of the globe. To do this Without otherwise interfering Witl theaction of the lantern when at rest is a difficult problem. 1 I have found that this can be readily accomplished according to my inventionby .providing a number of openings vsuch as 30 through `mitted and regulated by a battle member 31.

In the form shownin Fig. 1 I provide abaille member 31has` a flange 34 which is detachably secured in some suitable manner .Q to'thewall 27, as for instance, by 4means of a bayonet joint 35. This makes it possible to readily detach th'e shield or slip it up so as to facilitate-cleaning the Walls. The cylindrieal'portion 29 is preferably secured to thegilange 36 which extends upwardly from the ring 28-either permanently or by, means of, a bayonet joint 37. Air passage 38 is i provided to the perforatedfring 28 either `thi-ough ,or inside of the baille member 3l from the openings 32 maypass through the openingr 38 and. thence through the openf l, ings 30 into the top of the globe and thence to 'the flame. The flaring wind breaker dome (for instance the ring 2S) kin position to deflect. part ot' thc air which may be forced down through the. tube 2t) and pre- .ventit from directly striking the' flame. The wind breaker is preferably of l'ell-shape. and vhas a curved surface ,extending "from the lower end ol' the tube 29`dmrnwardly and outwardly toward the upper end of tho lglobe 1t. ln this way it is possible yto obtain the proper balance between the air supply and the combustion exits .so as te 'insure ``a steadyflame which requires just enough air to support combustion 'without an excess of air which would extinguish the flame. The member 39 also serves to deflect and asf :sistin uniforml' distributing air which is admittedthroug the `inlets 30 in the memfbeaie. l

VIn the form shown in Fig. 3' the openings 40 inV the lantern top are made su oiently large to serve not only as exits,V for the products of combustion but for inlets for airfin certain circumstances. theairfinlets 41 are in the tubular member .42'vvhichj-carries 'the `battling member 43,

which air from the lantern topcan be ad^ so that air.` which comes into theftop dome .tor and a bafllin 3l) is suspended from some-part, of the globe 3. Ina signal lantern, ato member h In this case and the air from inside the lantern is admitted through the opening 44 ben the baille member tothe openings 41.'

In the form of globe dome and holder i y, shown in Fig. 4 the, air inlets 45m-e in e. In

vertical Wall surrounded by a batlling memm .ber 46 While the air inlet 47 is formed los tween the upper inner edge of the baing member and the tubular member 48.

In the form shown in Fig. 5 theair ir lets I50 are formed in the horizontal ring of the globe dome and the bailling regulator 51 is secured to the tubularymember 52 leaving an airinlet 53 at its lower edge.

In vall of these constructions itwili be noted that what may be termed 'the emes gency air supply is furnished through the top 'of the lantern above the reflector it and that its, passage into the globe/domn i regulated by a battling member which eo trols the volume of' air to pass to the under certain conditions. I A i Notwithstanding the. small size or" is' new lantern it has been'found to Worlr with entire satisfaction with various fuel'oils and even under the most severe conditions o test. t i
